- This is I2C serial interface 16 bit I/O Expander Serial Module.
- MCP23017 can convert 16-bit parallel data into serial data of IIC interface and convert each other.
- Internal integrated power-on reset (POR) circuit reset to device default state.
- Two opposite programmable interrupt source outputs.
- Polarity flip register configures GPIO input polarity.
